While it is widely agreed that there are few greater pleasures on a twilight summer evening than sipping cocktails al fresco, the debate over what to drink will always cause controversy. Even the martini, the king of cocktails, has a bewildering array of variations.

Purists will stick with the traditional gin and dry vermouth, a fashionista may go for a mintini, a teenager a woowoo, a Harry Potter fan would likely be tempted by a mad eye – it is nigh on impossible to cater to all tastes without hiring a mixologist for the evening.

If martinis are on the menu, the best way to serve them is in a set of limited edition cocktail glasses. This summer, luxury gin brand Tanqueray No. Ten has teamed up with fashion designer Lara Bohinc to create a collection of hand-crafted crystal glasses with a white-gold plated cuff.

Bohinc’s inspiration for the glasses came from a building in Brasilia designed by architect Oscar Niemeyer. Bohinc designed the glasses to mirror the experience of drinking a cocktail: “The sand-blasted glass of the stem crescendos up to into the density of the metal coil, before you can finally relish the clarity of the glass.”

The glasses come with a 70cl bottle of Tanqueray No. Ten in a gift box, available from Harvey Nichols for £100 (€116), a treat for oneself or one’s cocktail companion.
